T-Mobile for example, got CPEs with CLAT that provide broadband via 3G/4G/5G,
but in general I don’t see other big players pushing the vendors for that. We
really must change that if we want to move on. Why we want competition if we
don’t ask them to support the standards? or we just believe the CPE is a
disposable cost and because that, we spend more CapEx and OpEx in other parts
of the network because the lack of vision when asking for CPEs?
In France, new broadband deployments are done with custom CPEs
supporting CLAT. Free is using MAP-E. Bouygues is using MAP-T. SFR
should also start using MAP-T, but this is unclear (for me) if they are
moving beyond the tests. And Orange started deploying DS-Lite.
On the mobile front, I don't know exactly, but I suppose many are doing
464XLAT, which is what is supported on both iOS and Android. There is
one exception that is still doing NAT44, but the function can be
colocated with the UPF and does not need to be very distributed.
